Why does a plant need roots a stem and leaves?

Answer 1

plants have these part because they are autotrophs which mean they make there own food. The roots bring up nutrients and water from the ground, and the leaves pull carbon dioxide from the atmosphere to create clorphyll. The biproduct of this process is oxygen. This process is called Photosynthesis. Plants also create gluclose, or sugar

Answer 2

A plant will not be able to thrive and flourish without the help of the roots, stems, and leaves.

The root system of a plant helps to anchor the plant to the soil and helps to absorb water and nutrients from the soil that is needed to support plant growth. The roots also help to store food, for example, in plants such as carrots, radishes, beetroots, parsnips the root acts as a storage structure.

The stem conducts water, minerals and food to the other parts of the plant. In some plants, green stems store food and in some others the stems themselves can produce food through photosynthesis. The stem also helps to support the plant structure and to bear the weight of the leaves, flowers, and fruits.

Leaves have a green color pigment called chlorophyll present in chloroplasts. The leaves capture energy from the sun and with the help of chlorophyll pigments and the carbon dioxide that enters the leaves through openings called stomata prepare food needed for plant growth.

The plant leaves synthesize and translocate the flower-inducing hormone called florigen to the buds. They store food on a short-term or a long-term basis depending on the climatic conditions in which they grow. The leaves help to cool down the plant when heat escapes with water that evaporates through the stomata present in the leaves.
